Grouped fields with vert. scroll revisited

[gyroscope]

Hi, another Forum member asked about vertical scroll to control two or more fields. If one groups the fields and gives a vertical scrollbar to the group, this scrolls the actual fields rather than taking control of the fields' vertical scrollbars.

For the Script Collector prog I'm working on, I'd like to give the user an option to show horizontal lines between the lines of script (as text) in a field. (So i have one field non-opaque for collecting the script, and another underneath showing/hiding the rules). I've used the following code to show rules depending on how many lines there are in the script field:

Code: Select all

on mouseUp
 put the number of lines in field "A" into tFnum
   answer tFnum
      put empty into field "B"
      repeat with tRun = 1 to tFnum
      put "_____________" into line tRun of field "B"
   end repeat
end mouseUp

That works OK but if the scrollbar is "activated" in the first field, showing the scroll button, and likewise the field showing the rules underneath, I'd like to link them with a vertical scrollbar which would scroll the text in the two fields in tandem, rather than the actual fields themselves.

Is this possible, does anyone know please

I believe you can insert a standalone scrollbar and make it do what you want.

check out scrollbarbeginning, scrollbarend, scrollbardrag, scrollbarlinedec, scrollbarlineinc, and all the other scrollbar* stuffs in the dictionary.


Lots of interesting stuff in there i'm still trying to get a handle on.

Hi sturgis,

Thanks for reminding me of those. I've still got the problem of the group vertical scrollbar moving the fields themselves rather than what's in them...I'm sure it involves some of the stuff you mentioned but can't work out how...

[sturgis]

How bout something like this?
edit: Don't know if you can do the same thing as this with the group scrollbar, but you can turn it off and add a seperate one and do as below.

Might be able to just turn on the scrollbar on one of the fields, not any others you want to layer and use this same code, but I used the scrollbar control seperately.
end edit

I have this script for the external scrollbar

Code: Select all

on scrollbarDrag newPosition
   set the vscroll of field "first" to newPosition
   set the vscroll of field "second" to newPosition
end scrollbarDrag

and this to adjust one of the scrollbar properties.

Code: Select all

set the thumbSize of scrollbar "Scrollbar1" to (the heigh of field "first" / the formattedHeight of group "first"

It works fine, both fields scroll at the same time, and since I have duplicate info in both I can confirm that they match up nicely.

Hey sturgis, that's real neat, thank you!

Sorry to be slow here but where do you put the other bit of code please

You're not slow, i'm typo king today. Just make the whole thing like this. Put it all in the scrollbar script.

This works only for dragging, would have to do similar to capture the line increment, page increment stuff. But for a quick example of just dragging the thumb to control several fields, this works.

Code: Select all

on scrollbarDrag newPosition
   set the thumbSize of me to (the height of field "first" / the formattedHeight of field "first")
   set the vscroll of field "first" to newPosition
   set the vscroll of field "second" to newPosition
end scrollbarDrag

edit:
To make the scrollbar look right you can also put

Code: Select all

set the startValue of me to 0
set the endValue of me to the formattedHeight of field "first"

It didn't seem to like those three lines in the scrollbarDrag handler (can't remember the error message) but the first bit of code works a treat for what I want, thank you!

By the way, the My Script Collector program this is for, I'll be "donating" to the Rev community when it's finished. I'll be putting a Thank You list in the splash screen so may I have your real name please, sturgis, to add to the list? (That's considering you want your name there, of course!)

I'm kinda a recluse through lack of choice, and also through active choice. So no need to add me to the list, just glad to help.

This forum here is about the most interaction I have with.. well. anyone.

Not many forums where I feel comfortable enough to actually type things in, so this community must be something special.

If you can post your error message, maybe I can figure out if I typo-ed something, and how to fix it. My typers are a bit recalcitrant some days so who knows what I meant to type as apposed to what I actually typed.

Yes, it's a friendly and helpful community, for certain. As Rev tends to be "three steps forward, two steps back" sometimes, there's always someone there to save the day.

It show no errors when compiling but then says "Object can't set this property" so I realised this was in a 3rd field (to use the scrollbar of it) rather than a Scrollbar object. So it works fine now.

Thanks again for your help, sturgis.
